This Acti9 electrical auxiliary is a modular OC and fault contact. The 2 contacts (2 NO/NC) can report the signalling information of the associated device to a programmable logic controller. The rated current (In) is from 2mA to 100mA with operating frequency of 50Hz to 60Hz at 24VAC to 250VAC, and from 2mA to 100mA at 24VDC to 220VDC. It has 2 position switches with contacts type 2 C/O. It is intended for new or renovated installation in small commercial, buildings, critical buildings, healthcare, industry, data center and infrastructures. This OC and fault contact is compatible with Acti9 ranges such as iC60, iID, iDPN ARC, iDPN Vigi, iDPN Vigi ARC, iSW, iC60 and iID double terminals residual current circuit breaker (RCCB). The OC and fault contact is installed for only Acti9 ranges such as iID, iDPN Vigi, iSW-NA, ARA, iC60 and RCA devices which includes 2 changeover contacts. If no comb busbar, also compatible with iC40, iC40 ARC, iCV40, iCV40 Vigi ARC. The iSD+OF is either used for device short name or compatibility code. The mechanical indicator is provided on the product for signalling (Local). It has a screw clamp terminal connection at top and bottom. The connection allows rigid copper cable.
